Comparing your ex ante to your ex post will give you a good idea about how good you are at forecasting things.Much of the hair splitting doesn't matter a whole lot after the purchase IMO.

I've been combing through the sites that list properties/lots for sale, and all that I've been able to find thus far are lots that zoned for SFR.

Personally, I wouldn't add hair to the deal now with the conventional offer.  

Take a GC and go over the house with a fine tooth comb if numbers still work ok and the house is ok then take it.

Maybe a hair more if lot rent is super cheap or if seller can finance large part of the sale.  

Worrying gives you ulcers & gray hairs.

FWIW I love owner financing and am planning a business model selling houses on owner financing, but I will work hard to be compliant.For some hair raising info about "enforcers" go to the last page of this mobile home thread:Mobile home safe act threadBTW the "police" will 99.9% be the borrower who feels they where ripped off and they call the authorities especially if they figure out the legal remedy is 90% of the time the investor loosing the title and equity in the deal.

This was for a Hair-care product. 

Essentially splitting hairs.

Possession can be a little hair but both parties own the real property having both legal and equitable title.
